The meagre 1,200-capacity Olympia might feel like a step down for Roan — this month the 26-year-old performed in front of the largest ever crowd at the Lollapalooza festival in Chicago, an estimated 110,000 people. Not that the Irish audience will lack for enthusiasm. Taylor Swift’s Dublin gigs sparked a frenzy earlier this year and Chappellmania is just as real.

The lack of tickets may not be garnering as much sympathy as it did when it came to Swifties, but it is causing mass hysteria among frustrated fans. Roan, whose real name is Kayleigh Rose Amstutz, has been working for the best part of a decade on what looks like an overnight success. She was thrust on to the phone screen of every Gen Zer when her single blew up on social media at the start of the summer.
